<abstract xmlns="http://www.w3.org/1999/xhtml"><p> The aim of the study was to determine the physical properties of gbafi lo fruit and kernel, namely, axial dimension, geometrical and arithmetic mean diameter, sphericity, aspect ratio, 1000 unit mass, surface area, true and bulk density, porosity angle of repose and coeffi cient of static friction. Investigation of physical properties of gbafi lo (<italic>Chrysobalanus icaco</italic>) is important for the design of appropriate equipment for processing, transporting, cleaning, sorting, packaging and storage processes.
